Description
The left shows a histogram of the trait self-control (TSC) test
score. The mean and 95% confidence intervals are visualized with the
vertical lines. The sampled data appears to be normally distributed with
a mean TSC score of 2.85, with a standard deviation of
0.56.
The top right figure shows the correlation between the different variables in the database. From the heatmap, can be seen that there is a strong negative correlation between the disturbances in sleep quality (PSQI) and concentration (CIS) score. And a negative relation between the alcohol usage (AUDIT) of the participants and the trait self-control score. A positive correlation can be found between the chronotype (MCTQ) and both the disturbances in sleep quality and alcohol usage (AUDIT).
